“Danielle and Marty are engaged,” the source says. “They’ve very happy!”

The source added that the engagement was filmed for the next season of Bravo’s Real Housewives of New Jersey. Staub previously exited the series following several explosive arguments with fellow housewife Teresa Giudice.

The couple has been dating since April 2016, and Caffrey frequently appears on the mom of two’s Instagram page.

“Here's to my #first year #anniversary with this cutie,” she captioned an Instagram pic on the couple’s recent anniversary. “You are a wonderful man and I'm blessed to have you in my life... #happyoneyear @marty_caffrey ?.”
